I want to control a 12Vdc pump in daylight. Can I reverse the electrical wiring from the sensor? or do I need a switch in-between

The controller pictured only passes current during dark hours. You could use an additional 12VDC relay (available from Amazon) with at least a single pole double throw set of contacts to power the pump. A plain switch in between will not do it. Good luck.

I would use 12volt dc relay. NC contacts would run pump during day light hours. Night hours relay would turn on and open contacts to turn pump off.

To be perfectly honest with you, if you aren't sure about wiring, maybe this isn't the right product for you. It will mean using trim tools and splicing to a found 12v wire. If you want to press forward, the red goes to a switched +12vdc source, and the black goes to a chassis ground point.Good luck.

No... I have mine wired directly to a on/off switch. A float switch is an option of course.

Yes you can. The sensor will cut the power to light/fan. Make sure you read instructions propoerly, specially the grounding.

I can't tell you how to wire your pump, but I can tell you that the float switch changes state from normally open to normally closed (and vice versa) by removing the retainer clip and inverting the float.

You cAre easily use I without the switch. And to wire it for reverse, either put in a fuse tap in the fuse box, simple cut it in to your break like (carefully).

for sure. or you can use a controller that changes it back to 12 volt. controller is key either way

I really do not remember. Since both the sensor(above) and the light(below) require power, that would suggest that the wires are more or less in the middle. Heath Zenith's customer service is pretty good so you might want to call them.

I have never seen that done before. I would just switch the hoses if I wanted to reverse the flow instead of switching polarity of the pump.

This control is made to plug in a 120 volt sump pump and will not work on 12 volt DC system.Dave

Clock/timer controled by AC - switch side is for DC - i used this for controling low voltage outdoor lighting

the only 12 volt source should be reverse light unless you introduce power from another source,i tied mine to fuse panel and put it on a switch,so i could check trailer coupling at any time

I'm using the switch as an on/off/auto for a electric car fan. It is double pole/double throw, so you can do two of something (fans, pumps, whatever) if you want. So it would be off/off, on/on, or auto/auto. If i understand you correctly you want to run the pump normally controlled from of a sensor "auto", then force "off" even if the sensor says to turn it on, and then also force "on" if the sensor says no. If that is the case then YES this switch will work. The switch completes the circuit in two positions, and is "open" in another position.

it should work just like your light switch, that is if there is no low voltage seepage from sensor switch.

There in normally no neutral on a standard light switch. Just hot and load. If you are luck there will also be a bare ground wire (often cut back so you will have to extend it). You can use the (extended) ground wire for both the neutral and ground connections on the sensor. As long as the circuit is not GFI protected then it works nicely. No adjustments required. Give it a minute to warm up. Try pressing the button once. The red light normally indicates it detected motion.

Yes, you could have ground and power reversed. Simply reverse the existing wires. If it used to work and now will not, you may have accumulated dirt/bugs/etc in the valve that is stopping the process from working. Time to take apart, carefully noting the sequence, and clean it up.
